      "This module contains a collection of YANG definitions for
supporting the Broadband Forum requirements on the management of
Quality of Service (QoS) as applicable to access network
equipment. As such, this module is specific to access network
equipment (e.g., BBF-specified Access Nodes and FTTdp DPUs).

Specifically, this module augments classifiers to manage the
policing of flows.
